Specification of Letters Patent.

To mZZ whom/ it TIMI/y concern: I

Be it known that we, CYPHER C. ELLIOTT and NOYES B. ELLIOTT, citizens ofthe United States, residing at Gilman, in the county of Marshall andState of Iowa, have invented a new and useful Chimney-Flue Thimble, ofwhich the following is a specification.

This invention relates to the thimbles for supporting stovepipes inchimneys, and has for its object to improve the construction, in creasethe efficiency, and decrease the labor and expense of construction ofdevices of this character and manner of installing the same in thechimney.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and general assemblage of the parts may beresorted to without departing from the principle of the invention orsacrificing any of the advantages,

In the drawings, Figure 1 is a front view of a portion of a chimney withthe improved device disposed therein and with the stovepipe intransverse section. Fig. 2 is a section on the line 2 2 of Fig. 1 withthe vertical staywebs connecting the casing and pipe-fine section inside elevation. .Fig. 3 is a side elevation of the parts shown inFig. 1. Fig. 4 is a perspective view of the improved thimble structurefrom the rear. Fig. 5 represents the pipe-clamping members detached.

In placing the ordinary circular thimbles for the stovepipes in chimneysit is necesssay to cut the bricks adjacent to the thimble and fit themaround the same and then cement them in position, and the labor andannoyance incident to this operation is consider- To avoid this laborand annoyance, as well as to increase the strength and durability of thethimble, the improved construction herein shown and described isprovided, consisting of a hollow casing 10, preferably of cast-iron,corresponding in shape with a plurality of the bricks, so' that it canbe built in with the chimney 11 without cutting any of the bricks, or,in other words, employed in the wall of the chimney in place of acertain number of the bricks.

The fine for the stovepipe (represented at 12) is formed integral withthe casing and extends centrally therethrough with the outer end of thecasing closed except for the entrance to the pipe-flue section.

The casing portion is long enough to extend inward from the face of thechimney a distance equal to the thickness of the plaster, (representedat 13,) so that the plaster-line will coincide with the face of thecasing. The pipe-flue section 11 is supported from the casing by radialribs 1 1, and the casing is also provided with lateral extensions 15 16,equal in size to one or more bricks and adapted to occupy the spaces oftwo of the bricks at the sides, as indicated. The extensions 15 16 willpreferably be long enough to extend through the side walls of thechimney, as shown by Figs. 1 and 3. v

A portion of the stovepipe is represented at 17 with the usual bead 18formed therein and bearing against the outer face of the casing andlimiting the inward movement, and to prevent the withdrawal of the pipea band formed in two parts 19 20 is employed for enclasping the pipeoutside the bead 18, the ends of the band members overlapping andsecured together by clamp-screws 21 22. The clamp-screws also extendinto the casing 10, as indicated, and thus secure the band to thecasing.

The overlapping ends of the members 19 20 are slotted, as at 23 24, toprovide means for adjusting the same to fit different sizes of pipes. Bythis simple means the pipe is firmly locked in position in the casing 10and can neither be forced farther into the flue nor withdrawn therefrom,as will be obvious.

The device is simple in construction, strong and durable, and materiallyincreases the strength of the chimney.

Having thus described the invention, what is claimed is A chimney-fluethimble comprising a hollow casing conforming to 'a plurality of thebricks of the chimney and adapted to replace the same and an integralflue-section extending therethrough for receiving the stovepipe, I asour own We have hereto affixed our signa- 1egndkletterall1 exgensioiisconforminig (tlo thg tures in the presence of two Witnesses.
